Dolly towing speed
I am new to the RV world so I'll ask those with more knowledge this question. I am towing a PT Cruiser with a Demco SS dolly that I found used but in excellent condition. When looking at the Demco web site I noticed it states to not exceed 55 mph when towing with their dolly. I have drove over the road truck for 42 years and don't remember seeing tow dollys running that slow. What is your take on this 55mph warning. Thanks

I keep my American Car Dolly at 62 MPH or under as it has Hi Run ST tires. I think most ST's are not designed or rated to run over 65. Its a comfortable speed and contributes to better reaction times. --- And every once n a while i am able to pass something
All that said the manufacturer may have a valid reason to keep it to 55 and you may want to check with them

Most of the ST tires seem to be rated at 65 mph max. Most U-Haul trailers have max speed of 45 or 55 mph on the fender, that you see in our mirror when you look back. I try to keep ours at 60-65 mph.

Something to think about while driving.
The California Drivers hand book say 55 if toeing.
I am not sure what the other States speed limit is but I don't think you would be stopped by any High Way Patrol Officers if you stay at 55.
Just a thought.
P.S. If you are in a hurry, leave a little earlier.

I have a Demco Kar Kaddy SS and set the cruse control at 62. So far 12,000 miles with no problems.

It's 55 to 60, because that's all the tires can safely take, especially in hot weather.

60-65 and check the tire and hub temps every couple of hours when I stop for something else. Seldom exceed 65 mph with the motorhome whether towing or not.

I try to keep 60 as well, with occasional 65 on a hill roll.

If the dolly tires are not overloaded and at the correct pressure, you should be able to run any speed you are comfortable it as long as it doesn't exceed what the tires are rated for. Just makes sense to keep the speed near 60-65 for general safety reasons.

I think the point is that the tires are rated for 65 mph maximum while a lot of folks seem to like to run 75. Those of us who pay attention back off a bit from the maximum.

Trailer tire come in different speed ratings.
From the FAQ on Carlisle's web site.
How fast can I travel on Carlisle trailer tires?
In the past, most trailer tires were rated at 62 or 65 mph. Today, some of our tires are "rated" (speed symbols) at 87 mph (N), some at 75 mph (L), some at 65 mph (J: ST tires) and some at 62 mph (J: non-metric tires).
Please remember that speed ratings are test speeds and not recommended driving speeds. The ratings apply only to the tire itself, and not a particular vehicle. The speed rating does not mean that the vehicle can be safely operated at the tire's rated speed.
We recommend driving no more than 60 mph when towing a trailer. Please always drive at a safe speed and abide by the posted speed limit.

I had a tandem dolly with tires rated for a certain weight. I was lower than the weight, but the tires heated up in 25 miles at 60 mph. I went to a higher rated tire with a lot of reserve and they ran just warm like they should. What comes on the dolly is not necessarily a good enough tire for the job.
